Saad Najmi f8c03d18ed Allow RCTBundleURLProvider to request an inline source map (#37878) (#38995)
Summary:
See: http://blog.nparashuram.com/2019/10/debugging-react-native-ios-apps-with.html
When using direct debugging with JavaScriptCore, Safari Web Inspector doesn't pick up the source map over the network. Instead, as far as I can tell, it expects you to pass the source URL at the time you load your bundle:  https://developer.apple.com/documentation/javascriptcore/jscontext/1451384-evaluatescript?language=objc . This leads to a very sub-par developer experience debugging the JSbundle directly. It will however, pick up an inline source map. Therefore, let's add a way to have React Native tell metro to request an inline source map.

I did this by modifying `RCTBundleURLProvider` to have a new query parameter for `inlineSourceMap`, and set to true by default for JSC.

[IOS] [ADDED] - Added support to inline the source map via RCTBundleURLProvider

Pull Request resolved: https://github.com/facebook/react-native/pull/37878

Test Plan:
I can put a breakpoint in RNTester, via Safari Web Inspector, in human readable code :D
